On Sept. 20, a 5.08 ct. round fancy pink diamond raked in $1,426,500, more than doubling its $700,000 estimate, at Sotheby’s New York’s Important Jewels auction.

The entire auction, which was predicted to bring in $14 million, earned a total of $16,383,856—just $100,000 shy of last year’s record for a September jewelry auction at Sotheby’s.

“While many of our top 10 prices came from American trade buyers, both signed jewels and stones under 10 cts. brought spirited bidding from collectors worldwide,” said Gary Schuler, head of Sotheby’s jewelry department in New York, in a statement. “Jewels from the estate of Kitty Carlisle Hart doubled their overall low estimate and were led by her beautiful art deco diamond sautoir that achieved $146,500.”
